The 45-45-90 triangular prism shown in the figure has an index of refraction of 1.45, and is surrounded by air. A ray of light is incident on the left face at an angle of A?¸ =48.0A?°. The point of incidence is high enough that the refracted ray hits the opposite sloping side.

$2113_The triangular prism has an index of refraction.png$

Calculate the angle at which the ray exits the prism, relative to the normal of that surface. Express your answer as a negative number if the angle is clockwise relative to the normal, and a positive number for a counterclockwise angle.

What is the maximum index of refraction for which the ray exits the prism from the right-hand side? (It may help to remember that sin(90° - θ) = cos θ
